To all whom t may concern:

Be it known that I, THOMAS SHERWOOD, a citizen of the United States,residing at Belchertown, in the county of Hampshire and State ofMassachusetts, have invented, certain new and useful Improvements inTurnbuckles, of which the following is a full and completespecification, such as Will enable those skilled in the art to which itappertains to make and use the same.

This invention relates to turnbucklesifor use in connection withhoisting apparatus and for similar purposes; andtfhobj'ectthereof is toprovide an imprlQlddvicacElthic/lass which is simple in construction andoperation and which is provideditlmloTgtulliu:allyadjustablesuspending-hook and the parts ofA lowing speciication,of which theaccompanying drawings form a part, in which-- p Figure 1 is a plan viewof my improved turnbuckle, and Fig. 2 a central longitudinal section.

In the drawings forming part of this speci- Iication the separate partsof my improvement are designated by the same numerals of reference ineach of the views, and in the practice of my invention. I provide aframe comprising parallel top and bottom bars 5 and 6, with the ends ofwhich are det-achably connected side bars 7. The side bars 7 arepreferably provided with outwardly-directed loopshaped handles 8, andthe top and bottom bars 5 and 6 are reduced at the ends and passedthrough corresponding eyelets or openings in the side bars 7, and saidside bars are connected with said top and bottom bars and held in placeby nuts 9. The top and bottom bars are enlarged centrally, as shown at10, and passed centrally therethrough is a screwthreaded shaft 11,provided at its upper or outer end with a hook 12, and said shaft islongitudinally adjustable in the block, as will be readily understood.

The lower bar 6 ot' the frame is provided with a yoke 13, which isdetachably connected therewith, and said yoke is provided with a hook14. In order to connect the yoke 13 with the bar 6, the said bar ispreferably provided at each side of the center thereof with reducedportions 15, and the opposite sides of the yoke 13 are provided at theirends with hooks 16,

which are adapted to engage With said reduced portions. Thisconstruction enables the yoke 13 to turn freely on thebar 6 and preventsthe longitudinal movement of said yoke on said bar.

The hook lliis swiveled to' the yoke 13, and

nected with ropes, cables, or other suspendingdevioes. I

The entire device is simple in construction and operation and perfectlyadapted to ac'- complish the result for which it is intended, and itwill be apparent that changes in and modiiications of the constructiondescribed may be made without departing from the spirit of my inventionor sacriicing its advantages.

Having fully described my invention, I claim as new and desire to secureby Letters Patent- 1. A device of the class described, comprising aframe, a screw-threaded and adjustable shaft passed longitudinallytherethrough and provided at one end with a hook, and a yoke connectedwith said frame and adapted to turn thereon in line with said shaft,said yoke being provided with a hook, substantially as shown anddescribed.

2. A device of the class described, comprising a frame composed ofparallel bars, side bars detachably connected therewith, a screwthreadedshaft passed longitudinally through said frame or through said parallelbars and provided at one end with a hook, and a yoke connected with andadapted to turn on one of said parallel bars in line with said shaft,said yoke being provided with a hook,substan tiallyv as shown anddescribed.

3. A device of the class described, comprising a frame composed ofseparate detachable parts, :t screw-threaded shaft passed through myinventionhave signed my name, in pres; said frame and provided at oneend with a ence of the subscribing Witnesses, this 22d day hook, and ayoke connected with said frame of June, 1899.

and adapted to turn thereon in line with said THOMAS SHERWOOD. 5 shaft,said yoke being provided with a hook, Witnesses:

substantially as shown and described. FERNANDO G. SHAW,
